SPECIFICATION forming part of Letters Patent No. 334,631, dated January 19, 1886.

Application filed September 18, 1885, Serial No. 177,470. (No model.)

To aZZ whom it may concern:

Be it known that I, ADOLPH G. O. ADLER, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Lamp-Brackets,of which the following is a specification.

My invention relates to improvements in lamp-brackets, and the object is to provide a portable and convenient lamp-bracket for temporary or permanent attachment to pianos or organs, and especially to that class of musical instruments known as upright pianos.

This object I accomplish in the manner and by the means hereinafter described and claimed, reference being made to the accompanying drawings, illustrating the invention, in which Figure 1 is a side elevation, part in section,showing my improved lamp-bracket when the parts are arranged to retain the lamp in an elevated position. Fig. 2 is a rear view of Fig. 1. Fig. 3 is a side elevation, part in section, showing the parts arranged to retain the lamp in its lowest position. Fig. 4 is a detached perspective view of the plate secured to the lamp-reservoir.

Similar letters indicate corresponding parts.

In the drawings, the letter A designates the base or support of my bracket, which consists of a suitably-cut sheet of metal, a-such as brasswhich is of a flexible nature, and can therefore be bent around the edge of the case A of the piano, so as to be thereby retained in position.

In order that the surface of the case may not be injured by contact with the metal, I line the surface of this sheet with some kind of soft fabric 12. To this flexible sheet is secured a bracket, 0, of a rigid material, which carries an upright post, B. It is easily perceived that this base or support A, which I shall hereinafter call the clamping-support, could be made rigid and of one piece of metal, so shaped that it could he slipped over the edge of the piano-case; but I prefer the previously-described arrangement, because a support so constructed can be fitted to any thickness of case. After the clamping-support is properly placed, the cover A of the instrument can be secured and allowed to bear upon the same.

0 is the supporting-rod, which is provided with a socket, c, at its lower end, which isadapted to fit over the post B on the clamping-support A, while its upper portion is bifurcated and hinged to lugs cl d, formed on a plate, D, secured to the body of alamp, E.

As shown in Fig. 1, the lamp is in an elevated position; and in order that it may be placed in a lower position when so desired I provide the plate D with a socket, D, which is adapted to fit the post B on the clamping-support 0, Fig.2. It will be observed that in order to thus retain the lamp in a low position the supporting-rod must be moved into a position where it will not interfere. For this reason I hinge the same at its upper end to the plate, as before described, so that it can be swung radially upward, Fig. 2, in which position it is held in place by a catch, 6, on a bar, F, formed integral with or secured to the plate D on the lamp. This extension-bar also serves to hold a shade (shown in dotted lines in Fig. 1) of any ordinary construction.

In order to place the lamp in itslower position, it is simply necessary to withdraw the supporting-rod C from the post B, to which it may be secured bya thumb-screw, f, swing it radially upward, and then wedge its upper end between the spring-leaves of the catch on the extension-bar E, and then fit the socket D over the post B.

It is evident that the clampingbracket could be provided with a socket instead of the post B, and the supporting-rod O and plate D would then necessarily be provided with suitable posts instead of sockets.

The plate D might be secured in any manner to the lamp-body; but I prefer to have that part of the lamp which faces the supporting-rod fiat, and provided with a dovetail which is fitted by a corresponding dovetail in the plate, and in practice I allow some space between the dovetails, which is filled with plaster-of-paris, whereby perfect security is attained.

What I claim as new, and desire to secure by bracket and the free end of the said supporting-rod and the extension being provided with post-and-socket constructions for connection, substantially as described.

2. The combination, with the bracket provided with a clamp and a vertical post, of a lamp-supporting plate provided with a socket and having a supporting-rod pivoted thereto, and having a socket in its free end for connection, substantially as described.

3. The combination, with a bracket provided with a clamp, of a lamp-supporting plate having a supporting-rod pivoted thereto and an extension proj ecting therefrom, said bracket and the free end of the said supporting-rod and the extension being provided with postaud-sockct construction, and a vertical catch on the lainp-supporti 11g plate, substantially as dc scribed.
